Object holding selected particles data for a specific range of rigid body ids. Use SetDataSyncFlag, SetAllDataSyncFlag, or RequestSyncedData to have the required data made available at the next tick. Each time Sync is called, the particles' data is copied and the sync flags cleared. Use HasSyncedData or RequestSyncedData to check which data is available at any one time.
